Originally conceived as a vocal solo for a classically trained soprano. Now, the vocal palette has been expanded for both SSAA and SATB (48024233) choirs. Along with the expanded number of voices, the style has also expanded to include a folk-like style for the lower voices, an angel-like quality for the upper voices and an accordian, wind instrument and percussion accompaniment to embellish the piano part. This can also be accompanied using the chord symbols for a more free and improvisatory affect.
